My phone can be paired with my car, and I can ask directions via Siri through the car mic and speakers, but as soon as maps launches it boots me back to the iPhone speakers! Ironically I have the inverse issue with music. If I have any music app active on my phone (not even playing) the car will immediately auto play the music even if the car audio was off when I was last driving. Does anyone else have these problems? I feel like it used to work and probably broke around ios9.
